UVITEX NFW 450% is a fluorescent whitening agent powder for textiles. It provides a slightly violet white shade and has high affinity for polyamide, wool, and silk fibers. It can be used in exhaust and continuous processing and provides excellent build-up and a very high brilliant white effect. It has good stability when used with reducing agents and hydrogen peroxide during bleaching.
DEFINITION: Pigment is a substrate in a particulate form which is insoluble in water but which can be dispersed in this medium to modify its color and light scattering properties. They are organic or inorganic coloring materials. They have no affinity to textile materials. They are fixed on the textile material with the help of binding agent in form a thin invisible coating.

Fabric softener (also called fabric conditioner) is used to prevent static cling and make fabric softer i.e. Softening agents are applied to textiles to improve their hand, drape, cutting and sewing qualities.Fabric softeners work by coating the surface of the cloth fibers with a thin layer of chemicals; these chemicals have lubricant properties and are electrically conductive, thus making the fibers feel smoother and preventing buildup of static electricity

Poly-Optic® 14-Series Casting Resins are two-part,
polyurethane systems formulated specifically for applications where
optical clarity is required. Castings are clear like water; however,
PolyColor dyes can be added to obtain clear, colored castings. PolyOptic systems, with low viscosities and long pot-lives, provide for easy
mixing, excellent detail penetration, and easy degassing, through
vacuum or pressure casting techniques, for bubble-free castings.

Storage yellowing
o Atmosphere composition in store, shop and home (NOX beside other pollutants)
o Humidity and temperature
o Heating and ventilation
o Storage time
o Illumination
o Ozone fading
Thermal yellowing
Causes for yellowing during heat setting or molding :
Decomposition of lubricants/spin finishes (yellowing of substances on the fibres)
Decomposition of cationic softeners (yellowing of substances on the fibres)
Reaction of monomers, oligomers or functional groups (yellowing of fibre itself)
Especially PA: migration of antioxidants from within the fiber to the surface. [ yellow reaction products with nitrous oxides, especially in gas heated stenters]
Yellowing of substances on the fibre :
Scouring the fabric prior to heat treatment
Pre-emulsifying of spin finishes and lubricants by padding with suitable products and washing off during subsequent dyeing/finishing (especially important in case of micro fibres)

Grote partijen zijn al een tijdje onderweg met retail media. Ondertussen worden in dit domein ook de kansen zichtbaar voor andere spelers in de markt. Maar met die kansen ontstaan ook vragen: Zelf retail media worden of erop adverteren? In welke fase van de funnel past het en hoe integreer je het in een mediaplan? Wat is nu precies het verschil met marketplaces en Programmatic ads? In dit half uur beslechten we de dilemma's en krijg je antwoorden op wanneer het voor jou tijd is om de volgende stap te zetten.

Marvin neemt je in deze presentatie mee in de voordelen van non-endemic advertising op retail media netwerken. Hij brengt ook de uitdagingen in beeld die de markt op dit moment heeft op het gebied van retail media voor niet-leveranciers.
Retail media wordt gezien als het nieuwe advertising-medium en ook mediabureaus richten massaal retail media-afdelingen op. Merken die niet in de betreffende winkel liggen staan ook nog niet in de rij om op de retail media netwerken te adverteren. Marvin belicht de uitdagingen die er zijn om echt aansluiting te vinden op die markt van non-endemic advertising.

APPLICATIONS
UVITEX
®
NFW 450% must be applied from soft water or in presence of a suitable complexing
agent.
Polyamide, wool, silk
Exhaust process: From slightly acid baths, preferably in presence of
stabilized sodium dithionite; can also be applied in a
weakly acid peroxide bleaching bath.
Continuous process: Pad-bake, pad-steam, acid shock or wash-whitening processes.
Cellulosic fibers
Exhaust process: From water with addition of electrolytes.
In the peroxide and reduction bleach.
Continuous process: By padding and in wash-whitening process.
Dissolving/diluting
Dissolve by pouring on hot water. Boil up briefly with live steam if necessary.
Solubility:
at the boil 250 g/l
in cooled liquor 65 g/l
Stock solutions should be kept away from the light; also substrates treated with the whitening
agent, as long as it is not fixed.

The pH can also be set at 4–5 by using 2 g/l ALBATEX®
AB-45 as a buffer.
A final neutralization of the residues of reducing agent (with approx . 0.5 ml/l hydrogen peroxide 35%) is
recommended to avoid unpleasant odour and yellowing during subsequent drying.
The addition of 2–3% STABILON®
CT can be recommended to protect white goods against storage yellowing
